Re: hp 830 g5 no power

See attached. Fix up the SOT-23 device so it is properly on the logic board.

1) What are the topside markings on this mosfet ?

2) which charger IC is onboard this logic board ?

3) Share all white silk screened markings on the logic board. Could not find anything in my schematic database with '830'.

I couldn't find the schematic.
I have the same problem with my motherboard, did you solve the problem?

This laptop does not power on, voltages as attached in the pictures below. Behind mosfet Q6000 I have 19v, 0v if measured in front(3 leg and gate), if i short the mosfet the laptop turns on, I have changed the mosfet it works fine on a different motherboard, I have also changed the charging ic intersil 9538h, same result. No short to ground exists within the same mosfet what could be the issue.
